Definitions

  • the invention relates to a fan with a housing which has a housing space which receives its fan wheel and a drive motor which drives the fan wheel and which is arranged in its receiving space which shields at least its electrical connections.
  • a known fan used for air circulation in a cooling space of a cooling device its drive motor driving the fan wheel is arranged together with the fan wheel in a housing space of the fan housing.
  • an additional housing is accommodated on the latter, which is arranged and fixed within the housing space which receives the fan wheel.
  • the invention has for its object to improve the housing of a fan according to the preamble of claim 1, in particular the installation of the drive motor for the fan that meets the VDE regulations, using simple, constructive measures.
  • the receiving space for the lifting motor is arranged outside the housing space receiving the fan wheel and is fixed to the housing, the fixed receiving space being at least largely inaccessible after mounting the housing on the wall.
  • the solution according to the invention eliminates the need for an additional motor housing covering the motor connection poles with regard to the relevant VDE regulations, which results in a significantly simpler and faster assembly of the fan module, so that the manufacturing costs for the latter are substantially reduced.
  • the logistics for the fan module are simplified by reducing the number of individual components.
  • the additional housing within the housing space accommodating the fan wheel an unimpeded air throughput from the inlet opening to the outlet opening of the housing is possible, as a result of which the performance of the fan module is significantly increased.
  • the housing space for the fan wheel and the receiving space for the drive motor are arranged one behind the other in the direction of the drive axis of the drive motor and are separated from one another by a partition wall which is at least closed in the area of the receiving space.
  • the assembly sequence of the fan module is particularly simple due to an additional reduction in the number of individual parts required for assembly if, according to a next preferred embodiment of the object of the invention, it is provided that the receiving space for the drive motor is also integrally formed on the housing.
  • This design also ensures a particularly compact and dimensionally stable structure of the housing.
  • the location of the receiving space for the drive motor cannot be faulty due to the assembly.
  • the drive motor is particularly securely accommodated with regard to the relevant VDE regulations with regard to the safety of touching the motor connection poles within the receiving space if, according to a next advantageous embodiment of the counterpart.
  • the receiving space can at least largely accommodate the drive motor.
  • the drive motor can be fixed particularly quickly within the receiving space and is particularly easy to replace in the event of damage if, according to a next advantageous embodiment of the object of the invention, it is provided that the drive motor is held in the receiving space by at least one releasable holding element.
  • the holding element is designed as a spring clip, which is able to interact with the drive motor on the one hand and with latching positions in the receiving space on the other hand.
  • the drive motor can be positioned within the receiving space in a preferred direction by the spring force of the spring clip, where running noises, such as vibrations or the like, are avoided in a particularly simple manner.
  • the receiving space is designed to be open on its side opposite the fan wheel and is mounted with its open side against a wall supporting the housing of the fan.
  • a cooling device with a fan arranged in its cooling space is particularly expedient if, according to a last preferred embodiment of the subject matter of the invention, it is provided that the fan is designed according to one of Claims 1 to 7.
  • FIG. 1 shows a section of a wall of a refrigerator with a fan that can be fixed thereon, behind the fan wheel of which there is a receiving space for the drive motor arranged therein, in a sectional illustration from the side and
  • Fig. 2 shows the fan in top view, in a sectional view.
  • FIG. 1 shows a section of a heat-insulating housing 10 belonging to a refrigeration device, which serves to receive a cooling space 11 and which is equipped for the purpose of its heat insulation with a heat insulation layer 12, which is produced between an outer lining (not shown) and a non-cutting shape of a plastic board Inner lining 13 is arranged.
  • This is provided near its ceiling wall 14, on its rear wall 15 opposite the refrigerator door, with a blind hole-like receptacle 16 for holding a fan 17 designed as an axial fan.
  • the fan 17 has a housing 18, which is constructed in two parts from plastic injection molding, the housing part 19 facing away from the rear wall 15 is designed in a shell-like manner, the shell bottom opposite the rear wall and serving as the front of the housing part 19 being equipped with air inlet openings 20, while at the free ends of the saddle ⁇ lenwill of the housing part 19 latching means for releasably retaining the housing part
  • the air inlet openings arranged on the housing part 19 open into a housing space 22 which is essentially formed by the shell-like design of the housing part 19 and which serves to receive a fan wheel 23.
  • a partition 25 belonging to a second housing part 24 already mentioned is provided, in the section of which is assigned to the top wall 14 a sleeve-like receiving bore 26 for receiving a fastening means 27 designed as a self-tapping screw is formed.
  • the partition wall 25 is equipped with openings 28 serving as air outlet openings, via which openings 28 are provided, through which the fan wheel passes through the air inlet openings
  • the partition 25 has a section with a closed wall
  • a shell-like receiving area 30 which is in the center of a shell-like receiving area 30 is provided with a through bore 31 and which serves as a boundary wall to the housing space 22 for a receiving space 32 provided within the housing part 24.
  • This is similar to a tube, the tube wall 33 surrounding the receiving space 32 on the jacket side is closed on its end face facing the housing space 22 with the closed-walled section 29 and the end section facing the rear wall 15 is provided with recesses 34 which are formed approximately opposite one another.
  • the receiving space 32 is used to completely accommodate a drive motor 35 which is provided with connecting contacts 36 arranged inside the receiving space 32 and which has a motor axis 37 which penetrates the through bore 31 and which engages with the fan wheel 22.
  • elastic bearing shells 38 are provided on the end faces of the motor housing that extend perpendicular to the motor axis 37.
  • these interact positively with holding shells, of which the holding shell arranged adjacent to the fan wheel 23 is formed by the shell-like receiving region 30 molded into the closed-walled section 29, while the holding shell opposite the receiving region 30 is made, for example, of plastic injection molding manufactured shell part is executed.
  • a holding element 39 designed as a leaf spring acts on this shell part, which is supported with the free ends of its legs 40 in the recesses 34 lying opposite one another and which has the end face of the drive motor 35 against the stationary, closed-walled section 29 due to the pretensioning force generated as a result of the support presses, whereby at the same time both the bearing shells 38 and the holding shell designed as a loose part are pressed against the motor housing.
  • the fan 17 equipped with the drive motor 35 and the fan wheel 33 is fastened in the cooling space 17 to the rear wall 15, in the vicinity of the ceiling wall 14 by means of the fastening screw 27 to be engaged with the receiving bore 26, the rear wall 15 being in the fastened state from the housing part 19 facing away from open section of the receiving space 32, so that the electrical connection contacts 36 of the drive motor 35 are arranged in the receiving space 32, which is now closed on all sides, and thus specifically prevents access to them even with long and slender means, such as screwdrivers or the like is.
